PRINTING APPARATUS.

Application filed .Tune 18, 19,25. Serial No. 38,035.

ldy invention relates to improvements in printing apparatus and particularly to apparatus tor removably securing printing devices in a type roll or the like. My invention has among its objects the prod tion ot apparatus ot the kind described, `which simple, reliable, compact and satisfactory for use wherever round applicable. A particular object ot the invention is to provide improved apparatus tor removably securing individual type, as distinguished irom linotype or printing slugs, in a type roll. Many other objects and acvautages ot the construction herein shown and described will be obvious to those skilled in the art "from tlle disclosure herein given.

To this end m f invention consists in the novel construction, arrangement and combination ot parts herein shown and described, and n'iore particularly pointed out in the claims.

Fig. (i is a perspective ot a detail part oi" my improved apparatus, a portion of said detail part being broken away -toillustrat'e the construction thereof.

I prefer to disclose my present invention in connection ivith my in'iproved printing machine, ivllch is more clearly shoivn and described in my co-pending application, Serial No. Tfr-hei, Filed October 3, 1924i. rl`he improved printing machine preferably comprises a trame 1, a type roll f3 and a platen or impression roll el. The in'ipression roll et may be provided with a tympan 2 and a feeding arc 2 arranged to cooperate with the type roll. rfhe envelopes or other matter to be printed are delivered betiveen the rolls 3 and It by suitable means described in the co-pending application, the rolls being driven by other suitable means also described in the co-pending application.

The type roll 3 is designed to carry any desired number of type 5, each type 5 bearing a single character in the illustrated embodiment of the invention. As sho-wn, the roll 8 has a groove 7 therein, the depth of the groove being such that when the type rest on the bottom surface T thereot', the faces or'f the type will be properly disposed to cooperate with the roll et. In accordance with usual practice, the side `tacos ot' the type are parallel and to maintain them in proper relation in the groove 7 I provide wedge-shaped spacers S which properly space and retain the type in printing positions. The spacers S preieial'iiy extend beyond the end type ot each line ot type, the lines being completed by quads yor blanl; type bars 5a. i do not limit myself to the arrangement shown, as, obviously, the spacers could be made to contorni to type ot any size and shape.

Will now describe the improved apparatus whereby I removably secure the type 5 in the printing roll 3, the printing roll S being particularly adapted to cooperate with the improved apparatus and being an `eI-:sential element of the invention only to the extent indicated in the appended claims.

As best shown in Figs. 1 and 3the printing roll 3 is provided with wedge-shaped slots 15, one ot the Wedge-shaped slots being disposed ou each side or' the groove 7. lneach ot the Wedge-shaped slots 15 l preterably provide a plurality ot Wedge-shaped members 16, the Wedge-shaped members it being removably and slidably mounted in the slots l5. The members 16 may be threaded on va rod 17, or the equivalent, which is preferably threaded in opposite directions as indicated at 18 and 19 so that. When the rod is revolved it Will move the members 16 toward or aivay from each other. One end of the rod 1T may be squared as at 2O so that it may be engaged by a Wrench or the equivalent when it is to be revolved. The members 16 may be provided with .pro-- jecting parts 21 formed With the inclined faces 22 arranged to engage apparatus described in the co-pending application, which apparatus is not mate-rial to the present disclosure.

The members 16 are adapted cto hold clamping members 25 n Contact with the type 5 disposed in the groove 7. As shown in Fig. 6, each clamping member 25 pret'- erably comprises an arcuate strip 26 having bent ends 27 Which may be inserted in the Wedge-shaped slots 15, the arcuate strip be- Elfi fil!

ing so formed that when the ends 2T are disposed in the slots l5 the strip will snugly lit the printing roll 3. lligidly secured to the arcuate strip 26 or formed integral therewith is a block or lug E29 adapted `to ride in the groove T, the lug 29 being oi less Width than the strip 2li so that the overhanging part of the strip may seat on the ends of the spacers and on the Ytop surfaces of' the quads iilling out the lines of type.

In practice the type 5 and the spacers 8 are iirst properly positioned` in the groove i". The clamping members are then positioned upon the printing roll 23, the clamping members being slipped on from the ends ot the roll. The members i6 and the rods 17 are then positioned in the wedge-shaped slots l5, the rods 17 being manipulated to draw the members l' tightly against the bent ends 27 ot the cliunping members which bear against the spacers 8 and (piads 5 and prevent accidental displacement oi the type 5 relative to the printing roll.

Having thus described n'iy invention, it is' obvious that various imn'iaterial inodih'cations may be made in the same Without departing from the spirit ci my invention; hence i do not Wish to be understood as limiting myself to the exact term, construction, arrangement and combination of parts herein shown and described, or uses nientioned.

TWhat l claim as new and desire to secure by Letters Patent is:

l. The combination with a type roll having a longitudinal type receiving groove therein, of means slidably mounted on the roll and projecting into the groove for holding the tyne in adjusted positions therein,`

L and means for clamping said last-mentioned means in the adjusted positions.

The combination wi th a type roll having a longitudinal type receiving groove therein, of means slidably mounted on the roll and projecting into the groove for holding the type in adjusted positions therein, and means spaced ifrom the groove for clamping said last-mentioned means in the adjusted positions.

The combination with a type roll having a longitudinal type receiving groove therein and longitudinal slots arranged one on each side ot the groove` ot' means projecting into the groove and into the slots for holding the type in adjusted positions in the groove, and means disposed in the slots for clamping the last-mentioned means in the adjusted positions.

il. The combination With a type roll having a longitudinal type receiving groove therein and longitudinal slots arranged one on each side of the groove, of means projecting into the groove and into the slots for holding the type in adjusted positions in the groove, and means slidably mounted in the slots for clamping the last-mentioned means in the adjusted positions.

The combination with a type roll having a longitudinal groove therein, of type arranged in the groove, quads arranged in the groove, he type being disposed intermediate the quads, and means slidably mounted on the roll and engageable W'th the top and side surfaces of the quads :tor clamping the type to the roll.

i0. The combination with a type roll having a longitudinal type receiving groove therein, oi a plurality oi spaced means movably mounted on the roll and arranged to project into the groove for holding the type in adjusted positions therein, and means i'or securing said last-mentioned means in the adjusted positions.

in testimony whereof, I have hereunto .signed my name.
